Abstract

A live content management method, a source device, and a sink device are provided. The live content management method includes storing live content in a storage unit of a source device if the transmission of the live content from the source device to a sink device is temporarily stopped. The live content management method may also include transmitting the live content stored in the storage unit of the source device to the sink device and then transmitting live content currently being broadcasted to the sink device via the storage unit of the source device, when receiving a request for resuming the transmission of the live content stored in the storage unit of the source device before a time-out for a command to stop the transmission of the live content stored in the storage unit of the source device. Accordingly, it is possible to provide various data transmission scenarios for a home network environment by efficiently managing live content even when the transmission of the live content via a home network has been temporarily stopped.
